Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an air conditioner, and particularly to an air conditioner used in a high place such as a crane operator's cab in a steel mill or a steel mill.

(Prior Art) This type of air conditioner has an integral frame structure in which frames b, b, . . . are disposed at each ridgeline portion of a casing a, as shown in FIG. Therefore, the frame b gets in the way, making it impossible to enlarge the service opening c on the condensing unit side for servicing the compressor, etc., and the service opening c on the condensing unit side and the cooler side. Since the outer plates e and f covered by d are simply fixed with screws, service handles g, g, etc. are provided to improve workability during attachment and detachment, leading to an increase in costs.

(Purpose of the invention) In view of the above problems, the purpose of the invention is to make the service opening provided in the condensing unit for servicing the compressor etc. as large as possible without increasing the number of component parts. The point is to make it.

(Structure of the invention) The structure of the invention is that a compressor and a condenser are built into a casing that has a frame on each ridgeline to form a condensing unit, and a front plate that is detachable on the front and top surfaces of the casing. and a frame that forms a front and upper opening for compressor service covered by a top plate and is located at the ridgeline between the front opening and the upper opening, and a frame on the front edge of the top plate, While a gutter-shaped locking frame is fixed, a locking piece that is locked to the locking frame is formed on the upper edge of the front plate, so that temporary locking can be performed when the front plate is attached or removed. It is characterized by what it did.

(Example) Hereinafter, an air conditioner according to an example of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1, this air conditioner 1 is used by being installed on the top surface of a crane operator's cab 2 in a steelworks, etc., and is a unit in which a condensing unit 3 and a cooler unit 4 are integrally combined. It is said to be a body type. Reference numerals 5 and 6 are ducts.

The condensing unit 3 is constructed by disposing a compressor 7, a condenser 8, a condenser fan 9, and a condenser fan motor 10 in a casing 11 on the condensing unit side. 4 is constructed by disposing a cooler 12, a cooler fan 13, and a cooler fan motor 14 in a casing 15 on the cooler unit side (see FIG. 2).

Each ridgeline portion of the casings 11 and 15 is provided with frames 16, 16..., and front plates 17, 1 on the condensing unit side and the cooler side are provided with respect to these frames 16, 16...
8, rear plate 19, 20, side plate 21, 22, top plate 2
3, 24, bottom plates 25, 26, and partition plate 27 are attached to form a box-like body (see Fig. 3).

The front plate 17 and rear plate 19 on the condensing unit side are provided with a cooling air inlet 28 and an outlet 29 made of wire mesh.

The cooler unit side plate 22 is provided with an air inlet 30 and an air outlet 31.

In the condensing unit 3, the front plate 17 and the front half 23a of the top plate 23 that cover the front and upper surfaces of the casing 11 are removable, and a front and upper opening 32 for compressor service is provided. It is said to be 33.

In this embodiment, the front half 23a of the top plate 23 is detachable, but it goes without saying that the entire top plate 23 may be detachable.

Then, the frame that should be located on the ridgeline between the front opening 32 and the upper opening 33 is removed,
The front and top openings 32, 33 define a series of large service openings.

A locking frame 34 having a gutter-like cross section is fixed to the front edge of the front half 23a of the top plate.

On the other hand, a locking piece 35 that is locked to the locking frame 34 is formed on the upper edge of the front plate 17 .

Thus, when the front plate 17 is attached or detached, the front plate 17 is temporarily locked by the engagement of the locking piece 35 with the locking frame 34. Reference numeral 36 is a projection for supporting the front end of the front half 23a of the top plate.

In this embodiment, the front plate 18 of the casing 15 on the cooler unit side is also removable and serves as an opening 37 for service.
A locking member 38 having an L-shaped cross section is provided on the frame 16 located on the ridgeline above the frame 7 . On the other hand, a locking piece 39 that is locked to the locking member 38 is formed on the upper edge of the front plate 18 . That is,
The front plate 18 on the side of the cooler unit 4 is temporarily secured when being attached or detached. In addition, the front plate 17,
18, the top plate 23, etc. are attached with screws 40, 40...

With this configuration, even if the crane is installed at a high place such as the top surface of the operator's cab 2, when the front plates 17, 18 and the front half of the top plate 23a are attached and detached during service,
Since the front plates 17 and 18 are temporarily fixed, screw 4
0, 40: There is no need to support the front plates 17, 18 by hand during removal, and work efficiency is improved.

(Effect of the invention) According to the invention, the condensing unit 3
A front and upper openings 32 and 33 for compressor service, which are covered by a front plate 17 and a top plate 23, are provided on the front and upper surfaces of the casing 11, and a ridgeline portion between the front opening 32 and the upper opening 33 is provided. Since the frame that should be located at the front is removed, the service opening can be made as large as possible, which has the practical effect of significantly improving serviceability.

Further, a gutter-shaped locking frame 34 is fixed to the front edge of the top plate 23, and a locking piece 35 is formed on the upper edge of the front plate 17 to be locked to the locking frame 34. Locking piece 3 for locking frame 34
By locking 5, the front plate 17 can be temporarily locked during installation and removal, so workability is good even if it is installed at a high place, and there is no need for service handles, etc. as seen in conventional examples. This also has the effect of reducing weight and cost.
